Mastervolt AC Master Inverter with UK Socket (12V / 2500W)

The Mastervolt AC Master power inverter produces a pure sine wave AC (Alternating Current) output from a DC (Direct Current) input from your boats battery bank. Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. The inverter is easy to install and features built in protection against over-temperature, overload, short circuit, high or low battery voltage and reverse polarity.

The power inverter is robustly built and delivers the full output even in demanding conditions. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming. It also features an automatic power saving mode, meaning a longer run time and less strain on your batteries. The 28212500 model is MasterBus compatible and can be used with remote control M70405080 for easy operation.

With the 2500 Watt model, you can use a 3 phase system, or combine up to 15 units in parallel for higher power outputs.
